What’s up with people on Facebook who put a picture of their child as their profile picture?

If this is a Facebook profile of lil’ Johnny Snotnose, it’s totally cool to have little Johnny’s picture as the profile. 
However if the Facebook Profile is for Mrs. Suzy Snotnose, please put a picture of yourself with your kid, or heaven forbid post a picture of JUST you!

You’re not being selfish for putting up a picture of youself as your profile.  That’s actualy what profile picture means.
I realize that your child is a HUGE part of your life, but putting a personal picture up doesn’t dehumanize him/her.  Trust me on this.
